Highly-increased photoluminescence of Pr3+ due to the Eu2+→ Pr3+ energy transfer in Al2O3 coatings formed by plasma electrolytic oxidation
(Journal of Luminescence, 2020)
In this paper, photoluminescence (PL) properties of Pr3+ single doped and Pr3+/Eu2+ co-doped Al2O3 coatings formed by plasma electrolytic oxidation of aluminum were investigated. The PL spectra of Al2O3:Pr3+ coatings feature ...
Dy3+ and Dy3+/Ce3+ doped Al2O3 coatings obtained by plasma electrolytic oxidation: Photoluminescence and energy transfer from Ce3+ to Dy3+
(Journal of Luminescence, 2020)
In this paper, Dy3+ and Dy3+/Ce3+ doped Al2O3 coatings were synthesized by plasma electrolytic oxidation process of aluminum. Structural and photoluminescence (PL) properties of obtained coatings as well as energy transfer ...
